8. What are four variables that determine population sizes?

9. Population change = (
+
) - (
+
)

10. What are the three age structure categories for an age structure diagram?

11. The size of a population will likely increase if it is made up of mostly

12. Species vary in their biotic potential or
.

13. What does r stand for?

14. No population can grow indefinitely because of limitations on
and
between species for those resources.

15. List the seven limiting factors mentioned in the textbook.

16.
is the combination of all factors that act to limit the growth of a population.

17. The biotic potential and environmental resistance determine the
or the
population of a given species that a particular habitat can sustain indefinitely without being degraded.

18.
or
starts slowly but then accelerates as the population increases.

19. Exponential growth has a
growth curve.

20.
involves rapid exponential population growth followed by a steady decrease in population growth until the population size levels off.

21. The logistic growth curve over time is a sigmoid or
curve.

22. Species with a capacity for a high rate of population increase (r) are called
species.

23. r-selected species usually have many
offspring and give them little or no

.

24. List 5 examples of r-selected species.

25.
tend to reproduce later in life and have a
of offspring with fairly
life spans.

26. Where do K-selected species typically develop?
